the same timepermitting the occupants ofk each seat to control the heatin proximity -larged View of the com ined heatin to such seat, so thatthe individual requirements of the passengersmay be met withoutinconveniencing the other passengers, provision being also made forVentilating the car in proximity to each seat with a' means which isalso subject to the control of the occupants of such seat.

To these and other ends the invention consists in certain parts andcombination of parts all of which will be hereinafter described, thenovel -features being pointed out inthe appended claims.

In the drawings: Figure 1 is an enlarged interior View of a portion of apassenger car showing the position of the heating` and Ventilating unitsrelative to the ca'r 'seats;Fig. 2 is an enlarged View of the piping,illustrating the controlling valve; Fig. 3 is a sectional View showingthe controlling Valves adjusted as to deliver steam ,from one car.

According to the illustrated embodiment of the invention, each carpreferably has a feed pipe 5d and a return pipe 3b4 arranged on theunder side thereof, and coupling devices of known construction (notshown) are adapted to attachably connect the feed and return pipes ofconnected cars.

To the end that each car may serve as the rear car of the train withoutaffecting the operation of the heating system, each car is preferablyprovided near each end with a bypass or connection 7 which is adapted toconnect the feed pipe 5d on any one ear with its return pipe 3b.Preferably this connection is located on. the inner side of two valves 8and 9 which are provided respectively in the pipes or connections 3b and5d for the purpose of closing such pipes at the ends of the car. Theconnection 7 may also have a Valve 10 which closes. the pipes 3b and 5dagainst communication when the valves 8 and 9 are open. Preferably asingle operating member is employed for simultaneously controlling thevalves 8, 9 and 10. In this instance, a lever 11 pivoted at l2 to thecar body has a slotted end 13 operating upon a projection 14 providedona valve operating crank 15, said crank being connected by links 16 and17 respectively to cranks 18l and 19 on Valves 8 and 10 respectively.

Within each car and preferably countersunk into the side wall thereofbetween the seats A are located the combined heating and Ventilatingunits. The construction of these units will be set forth hereinafter,only the heating member or radiator being at this time referred to andpreferably comprising a coil of piping 20, one end of which is connectedby a piping 21 to the feed pipe 5d while the other end is connected by apiping 22 to the return pipe 3". Avalve 23 may control the inlet to the,radiator while a Valve 24 controls'the outlet. It will thus be apparentthat the radiators are connected in parallel so that the condition ofone radiator does notvaffect the other radiators. In this way, thetemperature in proximity to one seat may be varied Without materiallyaffecting the temperature of the remaining portions of the car.

According to the present, embodiment of the invention, the radiators 2 0are each housed within a chamber 25 preferably formed within a casing26. The front wall of said chamber is an open work or reticulated plate27 which is substantially flush with the inner face of the side of thecar, v whereas the rear wall of the chamber25 is formed by a partition29 of cork or other suitable material which will act to deaden thesoundbetween the wheels and the interior of the car. The interior faces ofthe chamber 25 are preferably covered with asbestos or other heatnon-conducting sub- JJO stance, and air is admitted to the chamber 25 byway of openings 30 leading into the chamber 31 in rear of the chamber 25and having screens 32 thereover for excluding dust from the chamber 25and consequently from the interior of the car.

The chamber 31 has two openings 33 which are located at the bottom ofthe car vand partially inclosed by hoods 34, said hoods projecting belowthe car bottom and opening in opposite directions, so that, during thetravel of the car, the hood opening in the direction of said travel maybe employed for directing air into the chamber 31 and, by way of theports or openings 30, to the radiator chamber 25 where it is heated anddelivered to the car. Preferably when one hood is open the other isclosed for otherwise the latter would tend to suck the air from thechamber 31. To this end, valves 35 may be employed preferably in theform of plates hinged at 36 within the hood and adapted to swing toclose the openings l33, thevhoods thus serving to limit the movements ofthe valves. The controlling means for said valves comprises preferablylinks 37 each hinged at 38 to one of the valves 35 and also hinged at 39to one arm of a bellcrank lever 40 which is pvoted at 4l and extendsupwardly through the casing 26 where it carries a locking device in theform of a slide bolt 42 for coperation with a rack 43. The top wall ofthe casing 26 lies in a plane with the window sills of the car and formsportions of two adjacent window sills in that type of car where twoywindows separated by a stile are provided between two facing seats asin the ordinary Pullman car. In this way, the operating portions of thevalve controlling mechanisms are readily accessible to the occupants ofthe seats without interfering with the use of the window sills as armrests. The operating stems or members 44 of the valves 23 and 24 alsohave hand pieces 45 arranged above the casing 26 so as to be readilyaccessible.

The ventilation of the car is preferably effected by drawing air throughside walls of the car near the bottom and between the members of eachpair of facing seats so that the ventilation may be easily controlled bythe occupants of such seats without materi-I ally affecting thecondition of the air in proximity to the other seats. In the presentinstance, each of the casings 26 is provided with an ejector chamber 46having a screened outlet 47 on the outside wall of the car. The air tosaid chamber is admitted by lway of oppositely opening inlets 48 havingdust screens at their lower ends and merging into each other at thebottom of the chamber 46, the air therefrom being directed upon a roptary bladed Wheel or fan 49, the air hitting such wheel in a directionto cause the rotation thereof before passing through the not produce aproper suction through the passage 50. p

For the purpose of closing the ventilator, a valve is provided having aportion 51 for closing the exhaust opening and a portion 52 for closingboth of the inlets 48, said valve being slidably arranged within thevchamber 46 on guides 53 and 54 and having an operating portion 55extending into the car through a slot 56.

In the use of the invention, the cars are coupled together in the usualmanner, the flexible couplings of proximate cars being united, that is,the feed pipe on one car is joined to the feed pipe on another car, andthe return pipes being likewise connected. The lever 11 at the rear endof the rear car is turned to close the valves 8 and 9 and open the valvel0 so as to make connection between the feed pipe and return pipe,whereas levers 11 at other points on the train are shifted to controltheir respective valves 8, 9 and 10. Steam will then pass from one endof the train to the other and return to the boiler, thus making acomplete circuit. Any radiator on the train may receive steam from thiscircuit by opening its valves 23 and 24. The valves 35 for supplying airto the radiators are adjusted so that the hoods 34 opening inthedirection of travel of the train will supply air while the other hoodswill be closed, the adjustment being determined by the passengersoccupying the seats in proximity to such radiator. For opening orclosing the ventilators, the hand pieces 55 are employed.

An important result secured by the present inventionis that theindividual passen- `ger may control both the heating and the ventilationof the car in proximity to his seat. It is well'known, that rail-roademployees have a great deal of difliculty ininsane@ closing either orboth of the inlets of each air chamber independently of the otherchambers.
